Blackpool have signed Derby striker Kwame Thomas on a six-month loan.
Crawley have signed former Birmingham goalkeeper Callum Preston on a one-year contract.
Andre Villas-Boas has left Tottenham in the wake of their 5-0 home defeat to Liverpool.
The club said the decision was "by mutual consent" although after Villas-Boas said he would fight on following Sunday's loss, the move will be widely seen as a sacking.
A statement from the club on Monday morning read: "The club can announce that agreement has been reached with head coach, Andre Villas-Boas, for the termination of his services.
"The decision was by mutual consent and in the interests of all parties.
"We wish Andre well for the future.
"We shall make a further announcement in due course."
The Portuguese leaves with the White Hart Lane club seventh in the Premier League table, eight points off top spot and five outside the top four.
Villas-Boas, who replaced Harry Redknapp as Spurs manager in the summer of 2012, spent more than £100million in the summer transfer window, much of which was recouped by the sale of Gareth Bale to Real Madrid.
Despite plenty of talent being added to the squad, Spurs suffered a heavy 6-0 defeat at Manchester City last month and on Sunday were beaten 5-0 at home by Liverpool, a side considered serious rivals to them in terms of a top-four spot.
The search will now begin for another new manager for the North London club.
Former England boss Fabio Capello was immediately installed as Sky Bet's 4/1 favourite for the post after he was pictured at yesterday's game.
The bookmaker's other early contenders include Swansea chief Michael Laudrup, Guus Hiddink, Tim Sherwood and ex-boss Glenn Hoddle.
Villas-Boas had insisted on Sunday that he would not quit.
The 36-year-old said: "The call to make that decision is not mine, because obviously I won't resign and I'm not a quitter.
"The only thing I can do is work hard with the players to get them back on track.
"This is a top-four squad but in our Premier League form we are not there.''
Villas-Boas did lead Spurs into the last 32 of the Europa League - they won all six group games - and they are also through to this week's Capital One Cup quarter-finals. They host West Ham on Wednesday.
However, Premier League results have proved decisive with the Spurs board clearly unhappy that they are not closer to the top of the table.
Tottenham confirmed their former midfielder Sherwood will lead an interim coaching team.
In a short statement, Tottenham said: "The club can announce that Tim Sherwood, Chris Ramsey and Les Ferdinand will take charge of the first team whilst the club progresses discussions. Steffen Freund and Tony Parks continue as part of the coaching staff.
"Jose Mario Rocha, Luis Martins and Daniel Sousa leave the coaching staff and we wish them well for the future."
